CANNOT EDIT TEXT BY DOUBLE CLICK...

I CANT EDIT TEXT WITH A DOUBLE CLICK OF THE MOUSE, I'VE BEEN ABLE TO DO SO UP UNTIL TODAY. ALSO, WHEN I LOOK AT WHICH LAYER IS ACTIVE AND SELECT WHATEVER I FEEL ON THE SCREEN THAT IS THE LAYER IT APPEARS TO BE EXCEPT FOR IN THE PROPERTIES SCREEN IT IS ASSIGNED THE RIGHT LAYER AND BYLAYER. HOW DO I FIX THIS AND WHAT DID I DO SO I CAN AVOID THIS IN THE FUTURE?
